Remove the husks and silk of the corn cobs.
Boil the corn n a large pot of salted water for approximately 3 minutes, until the corn is no longer starchy.
Drain the corn and then immediately immerse it in a bowl filled with ice water. This will help preserve its vibrant color and stop the cooking process.
Set aside to cool down.
Cut the kernels off the cobs. Cut as close to the cob as possible to get the whole kernels.
Combine the corn kernels with the diced red onion, cider vinegar, olive oil, salt, and freshly ground black pepper.
Toss everything together to ensure the ingredients are well-mixed.
Garnish with fresh basil leaves on top of the corn mixture. The basil will add a delightful aroma and flavor to the salad.
Serve the corn salad chilled or at room temperature and enjoy the fresh and vibrant flavors!
